        the LensType value is obtained by splitting the stored value into 2
        integers:  The stored value divided by 4, and its lower 2 bits.  The second
        number is used only if necessary to identify certain manually coded lenses
        on the M9, or the focal length of some multi-focal lenses.

    # All M9 codes (two numbers: first the LensID then the lower 2 bits)
    # are ref PH with samples from ref 13.  From ref 10, the lower 2 bits of
    # the LensType value give the frame selector position for most lenses,
    # although for the 28-35-50mm (at least) it gives the focal length selection.
    # The M9 also gives the focal length selection but for other lenses the
    # lower 3 bits don't change with frame selector position except for the lens
    # shows as uncoded for certain lenses and some incorrect positions of the
    # frame selector.  The bits are zero for uncoded lenses when manually coding
    # from the menu on the M9. - PH
